Only 25? Amateur!

Yes it's normal. It probably is more rational to pay a bit more on craislist or ebay, and save gas and time. However, for some, it's the thrill of the hunt that motivates us. We obviously have nothing better to do. But when you find a steal, boy it all seems worth it! Your problem is that you want instant gratification and to actually get on the road with yor son. What's wrong with you?

I'll +1 cycleheimer on the luck thing. I go to far too many garage sales, on planned routes, but it's always the unplanned stray sale that turns up the goods. Oh, and 9 times out of 10, the sales that advertise bikes are selling department store garbage!

I lucked into a decent Centurion road bike yesterday that would meet your requirements. I'd let you have it at cost but I think 63cm is probably too large.
